I have been trying to restore my 1992 GMC K1500 truck and needed to replace the radio. GM in their infinite wisdom used a three part radio instead of the usual one piece design. No one makes a three part replacement but 1Factory Radio does a great job of restoring them. I have replaced both the Control Head and the Receiver Box from 1Factory Radio. The parts were plug and play and worked perfectly out of the box. The receiver had even been converted to accept IPOD aux input. I would definitely recommend this company for any of your electronic needs.
